The sampling adsorber also includes a first inner sealing ring 1031 of the adsorber and a second inner sealing ring 1032 of the adsorber, which are arranged between the core part 1002 and the outer cylinder part 1001 and fixed on the outer peripheral surface of the core part 1002. The adsorber first inner sealing ring 1031 and the adsorber second inner sealing ring 1032 are spaced apart and configured to: allow the core 1002 to move within the outer cylindrical portion 1001 while retaining the core 1002 and the The seal between the outer cylinder parts 1001, and when the sampling adsorber is in the first state, the first inner sealing ring 1031 of the adsorber and the second inner sealing ring 1032 of the adsorber are between the bypass channel inlet 1041 and the bypass channel outlet 1042 During this period, the first inner sealing ring 1031 of the adsorber is close to the bypass channel inlet 1041, and the second inner sealing ring 1032 of the adsorber is close to the bypass channel outlet 1042. The sealing ring 1031 blocks and thus enters the bypass channel inlet 1041 , flows out from the bypass channel outlet 1042 , and enters the downstream of the gap.
采样吸附器第一状态可以理解为采样吸附状态，即，包含要采集的样品的气体通过吸附部102时，样品被吸附部102吸附，而气体通过吸附部102进入所述间隙，随后被排出。The first state of the sampling adsorber can be understood as the sampling adsorption state, that is, when the gas containing the sample to be collected passes through the adsorption part 102, the sample is adsorbed by the adsorption part 102, and the gas enters the gap through the adsorption part 102 and is then discharged.
为了提高采样吸附的效率，可以在间隙的下游设置泵201，以便在间隙内形成抽吸的作用，加快气体进入吸附部102。In order to improve the efficiency of sampling adsorption, a pump 201 can be arranged downstream of the gap, so as to form a suction effect in the gap and accelerate the gas entering the adsorption part 102 .

Setting the adsorber sampling channel 108 is beneficial to collect the gas passing through the sampling adsorber. For example, when the pump 201 is used, the pump 201 can be connected to the outlet of the adsorber sampling channel 108 to facilitate gas suction. However, it should be understood that the sorber sampling channel 108 is not required.
在设置吸附器采样通道108的实施例中，还在吸附器采样通道108的入口的下游设置密封圈1034，以便阻止气体。In the embodiment where the adsorber sampling channel 108 is provided, a sealing ring 1034 is also provided downstream of the inlet of the adsorber sampling channel 108 in order to block gas.
在一个实施例中，通过所述芯部1002相对于所述外筒部1001移动，使得采样吸附器处于第二状态下：所述吸附器第一内密封圈1031位于旁通通道入口1041和旁通通道出口1042之间，吸附器第二内密封圈1032位于旁通通道出口1042的远离所述外筒部1001第一端的一侧，使得从旁通通道出口1042流出的气体被吸附器第二内密封圈1032阻挡而不能够进入所述间隙的下游部分。参照图4中的采样吸附器可以看到，吸附器第一内密封圈1031位于旁通通道入口1041和旁通通道出口1042之间，吸附器第二内密封圈1032位于旁通通道出口1042的右侧，这样从旁通通道出口1042流出的气体被吸附器第二内密封圈1032阻挡，因而，旁通通道104实际上被密封。此时，进入间隙内的气体不能继续通过间隙的下游部分，即间隙的右侧部分排出。In one embodiment, when the core part 1002 moves relative to the outer cylinder part 1001, the sampling adsorber is in the second state: the first inner sealing ring 1031 of the adsorber is located between the bypass channel inlet 1041 and the bypass channel. Between the outlets 1042 of the bypass channel, the second inner sealing ring 1032 of the adsorber is located on the side of the bypass channel outlet 1042 away from the first end of the outer cylinder part 1001, so that the gas flowing out from the bypass channel outlet 1042 is absorbed by the first end of the adsorber. Two inner sealing rings 1032 block access to the downstream portion of the gap. Referring to the sampling adsorber in FIG. 4, it can be seen that the first inner sealing ring 1031 of the adsorber is located between the bypass channel inlet 1041 and the bypass channel outlet 1042, and the second inner sealing ring 1032 of the adsorber is located between the bypass channel outlet 1042. On the right side, the gas flowing out from the outlet 1042 of the bypass channel is blocked by the second inner sealing ring 1032 of the adsorber, thus, the bypass channel 104 is actually sealed. At this time, the gas entering the gap cannot continue to be discharged through the downstream part of the gap, that is, the right part of the gap.
在一个实施例中，所述外筒部1001包括样品解析通道110，所述样品解析通道110能够允许气体从吸附部102流到外筒部1001外部。如图1所示，在外筒部1001的下侧，或，外筒部1001的与旁通通道104的不同位置，设置样品解析通道110。当吸附器采样吸附时，样品解析通道110被封堵，即，所述样品解析通道110的入口位于吸附器第一内密封圈1031和吸附器第二内密封圈1032之间，经过吸附部102的气体被吸附器第一内密封圈1031和吸附器第二内密封圈1032阻挡不能进入样品解析通道110。图1中，样品解析通道110的入口位于吸附器第一内密封圈1031的右侧，因而左侧的间隙内的气体被吸附器第一内密封圈1031阻隔。In one embodiment, the outer cylinder part 1001 includes a sample analysis channel 110 , and the sample analysis channel 110 can allow gas to flow from the adsorption part 102 to the outside of the outer cylinder part 1001 . As shown in FIG. 1 , a sample analysis channel 110 is provided on the lower side of the outer cylinder 1001 , or at a different position of the outer cylinder 1001 from the bypass channel 104 . When the adsorber is sampling and adsorbing, the sample analysis channel 110 is blocked, that is, the inlet of the sample analysis channel 110 is located between the first inner sealing ring 1031 of the adsorber and the second inner sealing ring 1032 of the adsorber, passing through the adsorption part 102 The gas is blocked by the first inner sealing ring 1031 of the adsorber and the second inner sealing ring 1032 of the adsorber and cannot enter the sample analysis channel 110 . In FIG. 1 , the inlet of the sample analysis channel 110 is located on the right side of the first inner sealing ring 1031 of the adsorber, so the gas in the left gap is blocked by the first inner sealing ring 1031 of the adsorber.
在一个实施例中，通过所述芯部1002相对于所述外筒部1001移动，采样吸附器处于第二状态，如图4或图5中示出的采样吸附器，此时，所述吸附器第一内密封圈1031和吸附器第二内密封圈1032位于样品解析通道110的入口的远离所述外筒部1001第一端的一侧，使得气体只能从所述间隙进入样品解析通道110，并通过所述样品解析通道110从外筒部1001排出。In one embodiment, by moving the core part 1002 relative to the outer cylinder part 1001, the sampling adsorber is in the second state, such as the sampling adsorber shown in Figure 4 or Figure 5, at this time, the adsorption The first inner sealing ring 1031 of the adsorber and the second inner sealing ring 1032 of the adsorber are located on the side of the inlet of the sample analysis channel 110 away from the first end of the outer cylinder part 1001, so that the gas can only enter the sample analysis channel from the gap 110, and discharge from the outer cylinder part 1001 through the sample analysis channel 110.
吸附器第二状态可以称为解析状态，即，吸附部102吸附的样品脱离吸附部102，从样品解析通道110排出采样吸附器。在吸附器第二状态，吸附器第二内密封圈1032位于旁通通道出口1042的右侧，这样从旁通通道出口1042流出的气体被吸附器第二内密封圈1032阻挡；同时，所述吸附器第一内密封圈1031和吸附器第二内密封圈1032位于样品解析通道110的入口的右侧，气体此时允许通过样品解析通道110的入口进入样品解析通道110，排出采样吸附器。简单说，此时样品不能够通过间隙流入图4或图5的右侧，而只能够通过样品解析通道110排出，被分析设备收集以便分析。The second state of the adsorber may be referred to as an analysis state, that is, the sample adsorbed by the adsorption part 102 is separated from the adsorption part 102 and discharged from the sample adsorption device through the sample analysis channel 110 . In the second state of the adsorber, the second inner sealing ring 1032 of the adsorber is located on the right side of the bypass channel outlet 1042, so that the gas flowing out from the bypass channel outlet 1042 is blocked by the second inner sealing ring 1032 of the adsorber; at the same time, the The first inner sealing ring 1031 of the adsorber and the second inner sealing ring 1032 of the adsorber are located on the right side of the inlet of the sample analysis channel 110, and the gas is allowed to enter the sample analysis channel 110 through the inlet of the sample analysis channel 110 at this time, and exit the sampling adsorber. Simply put, at this time, the sample cannot flow into the right side of FIG. 4 or 5 through the gap, but can only be discharged through the sample analysis channel 110 and collected by the analysis device for analysis.
本公开的采样吸附器通过以上的配置，可以通过简单地移动芯部1002而实现采样吸附状态和解析状态的切换，操作简单可靠。With the above configuration, the sampling adsorber of the present disclosure can switch between the sampling adsorption state and the analysis state by simply moving the core 1002 , and the operation is simple and reliable.
在以上实施例中，旁通通道入口1041和旁通通道出口1042在外筒部1001(沿外筒部1001的长度方向)的位置以及样品解析通道110的入口(沿外筒部1001的长度方向)的位置并不需要严格按照图1示出的位置设置，旁通通道入口1041和旁通通道出口1042之间的距离也不需要按照图1中示出的距离设置，只需要能够实现采样吸附器的第一状态和第二状态即可。In the above embodiments, the position of the bypass channel inlet 1041 and the bypass channel outlet 1042 in the outer cylinder part 1001 (along the length direction of the outer cylinder part 1001) and the inlet of the sample analysis channel 110 (along the length direction of the outer cylinder part 1001) The position does not need to be set strictly according to the position shown in Figure 1, and the distance between the bypass channel inlet 1041 and the bypass channel outlet 1042 does not need to be set according to the distance shown in Figure 1, it only needs to be able to realize the sampling adsorber The first state and the second state of .
例如，图1中示出，在第一状态下，吸附部102和芯部主体部之间的界面与旁通通道入口1041对齐，然而，这并不是必须的，图1示出的实施例仅为本公开的采样吸附器的一种可选的结构。For example, as shown in FIG. 1, in the first state, the interface between the adsorption portion 102 and the core body is aligned with the bypass channel inlet 1041, however, this is not necessary, and the embodiment shown in FIG. 1 is only It is an optional structure of the sampling adsorber of the present disclosure.
在一个实施例中，芯部主体部包括芯部主体部第二端，即图1的右侧的芯部主体部的端部。芯部主体部第二端的外部包括采样吸附器T型头107。相应地，所述外筒部1001包括位于外筒部第二端内部的滑槽109，采样吸附器T型头107能够在所述滑槽109内移动并采样吸附器T型头107的移动行程由所述滑槽109限定。也就是说，采样吸附器T型头107向左最多只能够运动到滑槽109的左侧端，向右最多只能够运动到滑槽109的右侧端。相应地，当采样吸附器T型头107抵接滑槽109的左侧端时，采样吸附器处于第一状态；采样吸附器T型头107抵接滑槽109的右侧端时，采样吸附器处于第二状态。In one embodiment, the core body portion comprises a core body portion second end, ie the end of the core body portion on the right side of FIG. 1 . The exterior of the second end of the core body includes a sample sorbent T-head 107 . Correspondingly, the outer cylinder part 1001 includes a chute 109 located inside the second end of the outer cylinder part, the T-shaped head 107 of the sampling adsorber can move in the chute 109 and sample the moving stroke of the T-shaped head 107 of the adsorber Defined by the chute 109 . That is to say, the T-shaped head 107 of the sampling adsorber can only move to the left end of the chute 109 at most to the left, and can only move to the right end of the chute 109 at most to the right. Correspondingly, when the T-shaped head 107 of the sampling adsorber abuts against the left end of the chute 109, the sampling adsorber is in the first state; device is in the second state.
通过以上采样吸附器T型头107和滑槽109的配合设计，可以方便操作，例如向左推芯部1002使得采样吸附器T型头107抵接滑槽109的左侧端时，即使得采样吸附器处于第一状态，向右拉芯部1002，使得采样吸附器T型头107抵接滑槽109的右侧端时，即使得采样吸附器处于第二状态。由此，提高了采样吸附器的操作便利和可靠性。Through the cooperative design of the T-shaped head 107 of the sampling adsorber and the chute 109, the operation can be facilitated. For example, when the core 1002 is pushed to the left so that the T-shaped head 107 of the sampling adsorber abuts against the left end of the chute 109, the sampling The adsorber is in the first state, and when the core part 1002 is pulled to the right so that the T-shaped head 107 of the sampling adsorber abuts against the right end of the chute 109 , the sampling adsorber is in the second state. Thus, the operational convenience and reliability of the sampling adsorber are improved.
在一个实施例中，采样吸附器还包括可拆卸地安装在外筒部1001端部的采样头101，所述采样头101配置用以刮擦被检查物体以便样品脱离待检查物体。采样头101可以通过螺纹连接至外筒部1001的左端。采样头101可以由硅胶材料形成，这样可以通过粘结带的方式粘接至外筒部1001的左端。In one embodiment, the sampling adsorber further includes a sampling head 101 detachably installed at the end of the outer cylindrical part 1001, and the sampling head 101 is configured to scrape the object to be inspected so that the sample is separated from the object to be inspected. The sampling head 101 may be screwed to the left end of the outer cylindrical portion 1001 . The sampling head 101 can be formed of silicone material, so that it can be bonded to the left end of the outer cylinder part 1001 by means of an adhesive tape.
如图2所示，采样吸附器靠近需要检查的物体表面，可以通过采样头101接触或刮擦物体表面，这样一些易脱落的样品被刮离物体，随后进入吸附部102被吸附部102吸附。采样头101可以由硅胶制成，从而硅胶采样头101可以粘附样品。在另一实施例中，采样头101内可以设置吸附剂，因而采样头101也可以吸附样品。As shown in FIG. 2 , the sampling adsorber is close to the surface of the object to be inspected, and the sampling head 101 can touch or scrape the surface of the object, so that some samples that are easy to fall off are scraped off the object, and then enter the adsorption part 102 to be adsorbed by the adsorption part 102 . The sampling head 101 can be made of silica gel, so that the silica gel sampling head 101 can adhere to the sample. In another embodiment, an adsorbent may be arranged in the sampling head 101 , so that the sampling head 101 may also adsorb the sample.
采用采样头101的设计是有利的，在采样过程中，用采样吸附器的前端的硅橡胶采样头101在需要被检测的人/物体上进行擦拭的同时，开启泵201进行气体的抽吸，以便吸附样品，延长采集时间可浓缩样品。It is advantageous to adopt the design of the sampling head 101. During the sampling process, the silicon rubber sampling head 101 at the front end of the sampling absorber is used to wipe the person/object to be detected, and the pump 201 is turned on to suck the gas. In order to adsorb the sample, prolonging the acquisition time can concentrate the sample.
在一个实施例中，所述吸附部102的两端可以设置筛网结构，以便过滤大颗粒固体，并且所述筛网结构与吸附部102可拆卸地连接，所述筛网结构将吸附剂固定在吸附部102内。例如，筛网结构与吸附部102采用螺纹配合，该设计不仅能允许拆卸筛网结构以方便吸附部102内吸附剂的更换，且采样时筛孔在允许气体通过的同时还能将大颗粒的粉尘挡在吸附部102外而防止污染。In one embodiment, the two ends of the adsorption part 102 can be provided with a screen structure to filter large solid particles, and the screen structure is detachably connected to the adsorption part 102, and the screen structure fixes the adsorbent in the adsorption unit 102 . For example, the screen structure and the adsorption part 102 are threaded. This design not only allows the disassembly of the screen structure to facilitate the replacement of the adsorbent in the adsorption part 102, but also allows the gas to pass through the screen while sampling large particles. The dust is kept out of the adsorption part 102 to prevent pollution.
在一个实施例中，采样吸附器还包括吸附器第三密封圈1033，固定在芯部第一端的外周面，吸附器第三密封圈1033允许吸附器102与外筒部1001相对移动时保持吸附器和外筒部1001之间的密封。设置吸附器第三密封圈1033是有利的，气体被吸附器第三密封圈1033阻挡，只能通过吸附部102进入采样吸附器，而不能够通过外筒部1001和芯部1002之间的间隙进入采样吸附器。In one embodiment, the sampling adsorber further includes a third sealing ring 1033 of the adsorber, which is fixed on the outer peripheral surface of the first end of the core, and the third sealing ring 1033 of the adsorber allows the adsorber 102 to maintain relative movement with the outer cylinder part 1001 The seal between the adsorber and the outer cylinder part 1001. It is advantageous to set the third sealing ring 1033 of the adsorber, the gas is blocked by the third sealing ring 1033 of the adsorber, and can only enter the sampling adsorber through the adsorption part 102, but cannot pass through the gap between the outer cylinder part 1001 and the core part 1002 Enter the sample adsorber.
在实际使用过程中，使用泵201是有利的，例如如图2所示，泵201通过例如波纹管连接芯部主体部采样通道108的出口，此时采样吸附器处于第一状态(采样吸附状态)，旁通通道104处于导通状态，泵201的抽吸作用在间隙内形成负压，采样吸附器左侧的气体被抽入采样吸附器，首先进入吸附部102，气体中的样品因而被吸附部102吸附，经过吸附部102的气体经由旁通通道104进入间隙的下游，随后进入芯部主体部采样通道108，被泵201抽走。In actual use, it is advantageous to use a pump 201. For example, as shown in FIG. ), the bypass channel 104 is in a conduction state, the suction of the pump 201 forms a negative pressure in the gap, the gas on the left side of the sampling adsorber is drawn into the sampling adsorber, and first enters the adsorption part 102, and the sample in the gas is thus The adsorption part 102 is adsorbed, and the gas passing through the adsorption part 102 enters the downstream of the gap through the bypass channel 104 , and then enters the sampling channel 108 of the main body of the core, and is sucked away by the pump 201 .
本公开的实施例还提供一种热解析腔装置，包括腔体，所述腔体限定热解析腔，所述腔体包括腔体第一端和与腔体第一端相对的开放的腔体第二端；所述热解析腔装置还包括隔板304，所述隔板304与所述腔体之间设置隔板密封圈3041，所述隔板密封圈3041配置成允许隔板304能够在热解析腔内移动的同时保持隔板304和所述腔体之间的密封；其中所述腔体包括载气入口301和载气出口302，使得在热解析腔装置的第三状态下，所述隔板304位于载气出口302的远离所述腔体第一端的一侧，载气能够从载气入口301进入热解析腔，从载气出口302排出。An embodiment of the present disclosure also provides a thermal analysis chamber device, including a cavity, the cavity defines a thermal analysis cavity, and the cavity includes a first end of the cavity and an open cavity opposite to the first end of the cavity The second end; the thermal analysis chamber device also includes a partition 304, a partition seal 3041 is arranged between the partition 304 and the cavity, and the partition seal 3041 is configured to allow the partition 304 to While moving in the thermal analysis chamber, keep the seal between the partition 304 and the cavity; wherein the cavity includes a carrier gas inlet 301 and a carrier gas outlet 302, so that in the third state of the thermal analysis chamber device, the The separator 304 is located on the side of the carrier gas outlet 302 away from the first end of the chamber, the carrier gas can enter the thermal analysis chamber from the carrier gas inlet 301 and be discharged from the carrier gas outlet 302 .
如图3，热解析腔装置由腔体构成，腔体限定了一个内部的空间，即热解析腔。此处，腔体第一端是腔体左侧的端部，腔体第二端是腔体的右侧的端部。如图所示，腔体的右侧的端部是开放的，通过腔体的右侧的端部可以进入热解析腔内。As shown in Fig. 3, the thermal analysis chamber device is composed of a cavity, and the cavity defines an inner space, that is, a thermal analysis cavity. Here, the first end of the cavity is the end on the left side of the cavity, and the second end of the cavity is the end on the right side of the cavity. As shown in the figure, the right end of the chamber is open, and the thermal analysis chamber can be entered through the right end of the chamber.
热解析腔装置还包括在热解析腔内的隔板304。隔板304可以沿腔体的长度延伸方向滑动，即隔板304可以在图3中左右移动。在隔板304和腔体的内壁之间设置隔板密封圈3041，这样隔板304左侧的气体不能进入隔板304右侧。The thermal analysis chamber device also includes a partition 304 inside the thermal analysis chamber. The partition 304 can slide along the length extension direction of the cavity, that is, the partition 304 can move left and right in FIG. 3 . A partition sealing ring 3041 is provided between the partition 304 and the inner wall of the cavity, so that the gas on the left side of the partition 304 cannot enter the right side of the partition 304 .
在一个实施例中，隔板304通过弹簧与所述腔体的所述腔体第一端连接，所述弹簧配置成在没有外力作用的情况下保持隔板304位于载气出口302的远离所述腔体第一端的一侧，并且允许在外力作用下，隔板304压缩所述弹簧并朝向所述腔体第一端移动，使得所述隔板密封圈3041位于载气入口301的靠近腔体第一端的一侧。在图3中，隔板304右侧被弹簧支撑，这样隔板304被保持稳定，并且在无外力作用下，隔板304不会向左移动；在隔板304被压缩后，撤去外力，隔板304将会被弹回初始位置，使得操作更加方便。换句话说，在使用的时候，只需要插入外部设备，待操作完成，拔出外部设备即可，而不需要认为操作隔板304或其他部件，使得操作过程简单。In one embodiment, the partition 304 is connected to the first end of the cavity through a spring, and the spring is configured to keep the partition 304 located away from the carrier gas outlet 302 without external force. One side of the first end of the chamber, and allow the diaphragm 304 to compress the spring and move toward the first end of the chamber under the action of an external force, so that the diaphragm sealing ring 3041 is located near the carrier gas inlet 301 One side of the first end of the cavity. In Fig. 3, the right side of the dividing plate 304 is supported by a spring, so that the dividing plate 304 is kept stable, and without external force, the dividing plate 304 will not move to the left; after the dividing plate 304 is compressed, the external force is removed, and the dividing plate The plate 304 will be bounced back to the original position, making the operation more convenient. In other words, when in use, you only need to plug in the external device, and then pull out the external device after the operation is completed, without thinking about operating the partition 304 or other components, which makes the operation process simple.
在一个实施例中，热解析腔装置还设置导向杆，导向杆与隔板304连接，具体地，连接在隔板304的左侧。导向杆可以是可伸缩杆，即导向杆自身收缩允许隔板304向左移动，当隔板304向右移动时，导向杆伸长，从而导向杆可以稳定隔板304的运动。在如图3所示的实施例中，导向杆是不可伸缩的，导向杆穿过热解析腔装置的腔体左侧端部，并且可以在腔体左侧端部的孔往复移动，以便隔板304的左右移动。在导向杆和腔体左侧端部的孔壁之间设置导向杆密封圈，以阻止腔体内外的气体流通。然而，应该知道，导向杆并不是必须的，隔板304不需要导向杆也可以在腔体内左右移动。In one embodiment, the thermal analysis chamber device is further provided with a guide rod, and the guide rod is connected to the partition 304 , specifically, connected to the left side of the partition 304 . The guide rod can be a telescopic rod, that is, the guide rod itself shrinks to allow the partition 304 to move to the left, and when the partition 304 moves to the right, the guide rod stretches, so that the guide rod can stabilize the movement of the partition 304 .

In other words, the moving range of the partition 304 may be limited by the heat insulating disk 305 . That is, the partition plate 304 will not move to the right side of the heat insulating disk 305 without the action of external force.
设置热腔303和冷腔306是有利的，一方面，设置冷腔306能保证吸附有样品的采样吸附器在被推入热解析腔设备的热腔303前不至被加热解析；另一方面，也能保护操作者在将采样吸附器插入热解析腔中和/或与驱动电机上时，免于烫伤。It is advantageous to set the hot chamber 303 and the cold chamber 306. On the one hand, the cold chamber 306 can ensure that the sample adsorber adsorbed with the sample will not be heated and analyzed before being pushed into the hot chamber 303 of the thermal analysis chamber equipment; , also protects the operator from burns when inserting the sample adsorber into the thermal desorption chamber and/or on the drive motor.

In order to improve the heating and heat preservation effect, the outermost layer of the heat chamber 303 can be coated with insulation cotton or other heat preservation materials; the heat insulation materials can improve efficiency, save energy, and prevent the operator from being burned by the heat chamber 303 of the thermal analysis chamber device. In other embodiments, the heater may be a resistance wire heater disposed around the thermal cavity 303 to increase the temperature of the thermal cavity 303 .
本公开的实施例还提供一种采样模块，包括上述的采样吸附器和热解析腔装置。An embodiment of the present disclosure also provides a sampling module, including the above-mentioned sampling adsorber and a thermal analysis chamber device.
所述采样吸附器能够通过开放的腔体第二端插入所述热解析腔装置的冷腔306内，使得采样吸附器的外筒部1001的外筒部1001第一端通过外筒部1001第一端的外周面上的外筒部第一密封圈1035抵接所述绝热盘305。本实施例的采样模块，可以方便地将采样吸附器和热解析腔装置分离和组装，从而方便单独使用采样吸附器采集样品。The sample adsorber can be inserted into the cold chamber 306 of the thermal analysis chamber device through the second end of the open cavity, so that the first end of the outer cylinder part 1001 of the outer cylinder part 1001 of the sample adsorber passes through the second end of the outer cylinder part 1001. The first sealing ring 1035 of the outer cylinder portion on the outer peripheral surface of one end abuts against the heat insulating disk 305 . The sampling module of this embodiment can conveniently separate and assemble the sampling adsorber and the thermal analysis chamber device, so that it is convenient to use the sampling adsorber alone to collect samples.
如图4所示，采样吸附器插入热解析腔装置内，外筒部1001的左端外周和热解析腔装置的绝热盘305之间由外筒部第一密封圈1035密封，从而绝热盘305左侧的气体不能够从采样吸附器和绝热盘305之间的间隙进入热解析腔右侧。As shown in Figure 4, the sampling adsorber is inserted into the thermal analysis chamber device, and the outer circumference of the left end of the outer cylinder part 1001 and the heat insulation disk 305 of the thermal analysis chamber device are sealed by the first sealing ring 1035 of the outer cylinder part, so that the heat insulation disk 305 left The gas on the side cannot enter the right side of the thermal analysis chamber from the gap between the sampling adsorber and the adiabatic disk 305 .
如图4所示，当所述采样吸附器插入所述热解析腔装置的冷腔306内，热解析腔装置的加热杆308接触并施加力至所述采样吸附器的吸附部102，使得吸附部102在所述外筒部1001内移动，直到采样吸附器T型头107被滑槽109的第二端阻挡，采样吸附器处于第二状态。采样吸附器的芯部1002被隔板304上的向右突出的加热杆308顶住，随着采样吸附器向左移动，芯部1002被加热杆308顶住，也就是说，芯部1002相对于外筒部1001向右移动，知道采样吸附器T型头107被滑槽109的第二端阻挡。As shown in Figure 4, when the sampling adsorber is inserted into the cold chamber 306 of the thermal analysis chamber device, the heating rod 308 of the thermal analysis chamber device contacts and applies force to the adsorption part 102 of the sampling adsorber, so that the adsorption The part 102 moves inside the outer cylindrical part 1001 until the T-shaped head 107 of the sampling adsorber is blocked by the second end of the chute 109, and the sampling adsorber is in the second state. The core 1002 of the sampling adsorber is supported by the heating rod 308 protruding to the right on the partition 304, and as the sampling adsorber moves to the left, the core 1002 is supported by the heating rod 308, that is to say, the core 1002 is relatively When the outer cylinder part 1001 moves to the right, it is known that the T-shaped head 107 of the sampling adsorber is blocked by the second end of the chute 109 .
当采样吸附器继续向左移动，即，所述采样吸附器插入所述热解析腔装置的热腔303，所述采样吸附器的吸附部102不能够相对于外筒部1001向右移动，此时，芯部1002和外筒部1001一起向左移动，因而，吸附部102将施加力至加热杆308使得加热杆308连同隔板304朝向热解析腔装置的腔体左侧移动，直到所述热解析腔装置处于第三状态。在热解析腔装置处于第三状态时，外筒部1001第一端的外周面上的外筒部第一密封圈1035在所述热腔303内沿所述热腔303的内壁滑动，直到位于载气入口301和载气出口302之间。When the sampling adsorber continues to move to the left, that is, the sampling adsorber is inserted into the thermal chamber 303 of the thermal analysis chamber device, the adsorption part 102 of the sampling adsorber cannot move to the right relative to the outer cylinder part 1001, and thus , the core part 1002 and the outer cylinder part 1001 move to the left together, thus, the adsorption part 102 will apply a force to the heating rod 308 so that the heating rod 308 together with the partition plate 304 moves toward the left side of the cavity of the thermal analysis chamber device until the The thermal analysis chamber device is in the third state. When the thermal analysis chamber device is in the third state, the first sealing ring 1035 of the outer cylinder part on the outer peripheral surface of the first end of the outer cylinder part 1001 slides along the inner wall of the heat chamber 303 in the heat chamber 303 until it is located Between the carrier gas inlet 301 and the carrier gas outlet 302 .
如图5所示，此时，所述隔板304位于载气出口302的左侧，载气能够从载气口进入热解析腔；并且，载气被外筒部第一密封圈1035阻挡不能够从外筒部1001和热解析腔装置的腔体之间通过，只能进入采样吸附器的吸附部102，随后进入样品解析通道110，从样品解析通道110的出口排出，最后从载气出口302排出。As shown in Figure 5, at this time, the partition 304 is located on the left side of the carrier gas outlet 302, and the carrier gas can enter the thermal analysis chamber from the carrier gas port; and the carrier gas cannot be blocked by the first sealing ring 1035 of the outer cylinder part Passing between the outer cylinder part 1001 and the cavity of the thermal analysis chamber device, it can only enter the adsorption part 102 of the sampling adsorber, then enter the sample analysis channel 110, discharge from the outlet of the sample analysis channel 110, and finally exit the carrier gas outlet 302 discharge.
在解析过程中，加热杆308可以升高温度，从而直接升高采样吸附器的吸附部102的温度，促进吸附部102上富集的样品脱离吸附部102。同时，热腔303的控温装置升高热腔303的温度，使得热腔303内的温度保持在所需温度，吸附部102和/或采样头101上富集的样品被加速解析。此时，载气从载气入口301进入，穿过吸附部102带走样品，最后由载气出口302运送至分析设备，例如离子迁移谱仪。During the analysis process, the heating rod 308 can increase the temperature, thereby directly increasing the temperature of the adsorption part 102 of the sampling adsorber, and promoting the enriched sample on the adsorption part 102 to detach from the adsorption part 102 . At the same time, the temperature control device of the thermal chamber 303 raises the temperature of the thermal chamber 303, so that the temperature in the thermal chamber 303 remains at the desired temperature, and the analysis of the enriched sample on the adsorption part 102 and/or the sampling head 101 is accelerated. At this time, the carrier gas enters from the carrier gas inlet 301 , passes through the adsorption unit 102 to take away the sample, and finally is transported to an analysis device, such as an ion mobility spectrometer, through the carrier gas outlet 302 .
在本公开的实施例中，由于采样过程中硅胶采样头101及吸附剂均处于室温，有利于被测样品的采集和富集；而解吸过程中由于热解析腔内的温度可以控制在80℃～300℃范围，被推入热解析腔中的吸附剂材料被迅速加热，有利于吸附剂中被吸附的样品的析出或脱离，同时经预热的载气在解析腔内能与析出的样品气体迅速混合，样品被载气有效地带出热解析腔，进入分析设备中，例如被运送至离子迁移谱/色谱-离子迁移率谱进行分离检测。In the embodiment of the present disclosure, since the silica gel sampling head 101 and the adsorbent are at room temperature during the sampling process, it is beneficial to the collection and enrichment of the sample to be tested; and during the desorption process, the temperature in the thermal analysis chamber can be controlled at 80°C In the range of ~300°C, the adsorbent material pushed into the thermal analysis chamber is heated rapidly, which is beneficial to the precipitation or detachment of the adsorbed sample in the adsorbent, and the preheated carrier gas can be combined with the precipitated sample in the analysis chamber. The gas is mixed rapidly, and the sample is effectively taken out of the thermal analysis chamber by the carrier gas and enters the analysis equipment, for example, it is transported to ion mobility spectrometry/chromatography-ion mobility spectrometry for separation and detection.
在一个实施例中，隔板304内还可以设置加热器以辅助升高吸附部102的温度。In one embodiment, a heater may also be provided in the partition 304 to assist in raising the temperature of the adsorption part 102 .
在一个实施例中，外筒部1001的外周还包括止挡部131，所述止挡部131配置成在所述热解析腔装置处于第三状态时能够抵接热解析腔装置的绝热盘305以便阻止采样吸附器继续朝向热解析腔装置第一端移动。设置止挡部131是有利的，当止挡部131抵接绝热盘305时，即表明采样吸附器被推送到位，热解析腔装置处于第三状态，可以开始热解析。此外，在一个实施例中，止挡部131也可以作为驱动部件，例如，使用驱动电机驱动止挡部131，使得采样吸附器在热解析腔内移动。In one embodiment, the outer circumference of the outer cylinder part 1001 further includes a stopper 131 configured to be able to abut against the thermal insulation plate 305 of the thermal analysis chamber device when the thermal analysis chamber device is in the third state In order to prevent the sampling adsorber from continuing to move toward the first end of the thermal analysis chamber device. It is advantageous to provide the stopper 131. When the stopper 131 abuts against the adiabatic plate 305, it means that the sampling adsorber is pushed into place, and the thermal analysis chamber device is in the third state, and the thermal analysis can be started. In addition, in one embodiment, the stopper 131 can also be used as a driving component, for example, a driving motor is used to drive the stopper 131 so that the sample adsorber moves in the thermal analysis chamber.
在一个实施例中，所述采样吸附器包括可滑动套环106，所述可滑动套环106套在外筒部1001外周，并且能够配合至所述热解析腔装置的所述腔体的第二端附近的卡口内，同时允许外筒部1001在热解析腔装置内移动。In one embodiment, the sampling adsorber includes a slidable collar 106, the slidable collar 106 is sleeved on the outer periphery of the outer cylinder part 1001, and can be fitted to the second chamber of the thermal desorption chamber device. In the bayonet near the end, the outer cylinder part 1001 is allowed to move in the thermal analysis chamber device at the same time.
在本公开中，设置了多个密封圈，这些密封圈可以由耐高温的氟橡胶形成。这些密封圈是可更换的。In the present disclosure, a plurality of sealing rings are provided, and these sealing rings may be formed of high temperature resistant fluororubber. These seals are replaceable.
